proj4js not convert y

Question

Proj4js.defs["EPSG:2322"] = "+proj=tmerc +lat_0=0 +lon_0=36 +k=1 +x_0=500000 +y_0=0 +ellps=intl +units=m +no_defs ";

Proj4js.defs["EPSG:4326"] = "+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs";

alert(feature.geometry.getVertices()[0].x);
alert(feature.geometry.getVertices()[0].y);
var point = new Proj4js.Point(feature.geometry.getVertices()[0].x, feature.geometry.getVertices()[0].y);


//Define the source Coord Sys 
var src = new Proj4js.Proj("EPSG:4326");
//Define the destination Coord Sys   
var dst = new Proj4js.Proj("EPSG:2322");

var gk=  Proj4js.transform(src, dst, point);
alert(gk);

i can get x and y cordinates but when i convert them to epsg 2322. x will change but y is always zero.

i found thats code but it is not converting correct

Answer 1

I'd add the +towgs84 parameters in EPSG:2322 definition in order to have a quite correct transformation (accuracy: 2 meters), as reported here (EPSG Geodetic Parameter Dataset):

Proj4js.defs["EPSG:2322"] = "+proj=tmerc +lat_0=0 +lon_0=36 +k=1 +x_0=500000 +y_0=0 +ellps=intl +units=m +towgs84=-84.1,-101.8,-129.7,0,0,0.468,1.05 +no_defs";
